佛說觀佛三昧海經 3.42

3.42

The Buddha told the Śākya sons: "You should now recite the names of the past Buddhas and pay homage to the Buddhas; also invoke your father's name and pay homage to the past Buddhas; also recite my name and pay homage to me; and in the future there will be a Buddha named Maitreya, to whom you should also pay homage. Acknowledge your sins of wrong views from past lifetimes. Now that the Buddha is currently in the world and the assembly of śramaṇas has all gathered like clouds, you should disclose and repent your faults before the Saṅgha of venerable monks, comply with the Buddha's words to repent your various sins, and in the presence of the assembly of the Buddha's Dharma, throw your five limbs to the ground like the collapse of Mount Tai. Repenting before the Buddha, your mind's eye will be opened, and you will see the Buddha's form-body, dignified, wondrous, and subtle, like Mount Sumeru brilliantly illuminating the great ocean."
